PRINTING-TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 477,383, dated June 21, 1892.

Application filed May 27, 1891.

T0 aZZ whom it may concern.-

Be it known that 1, CHARLES J. REED, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey,have made a new and useful invention in Printing-Telegraphs, of which the following is a specification.

My invention has for its object the combination of a telegraph-circuit with two or more type-writing machines of well-known form in such manner that the operators thereof may be located at different stations and be enabled to transmit and receive type-Written messages at will. I accomplish these objects by the arrangement of parts hereinafter described, but particularly pointed out in the claims which follow this specification.

In order that my invention may be fully understood, reference is had to the accompanying drawings, in Which- Figure 1 represents a diagrammatic view illustrating two stations, at one of which an operator is supposed to be transmitting and at the other an operator receiving. Fig. 2 represents a plan view showing the circuit connections of the apparatus and the arrangement of the electro-magnets which control the type-writer levers of any well-known form of type-writing machine.

Referring to the drawings in detail, A representsatransmitting-station,and B a receiving-station L, an ordinary telegraph-line j oining the two stations and connected at each end through contact-springs O O with a pair of distributers D, such as are well known and in general use in connection with multiplex synchronous telegraphs.

Each instrument is provided with a series of key-levers K of conducting material, pivotally secured to the frame F and provided at their inner ends with conducting-rollers 1), adapted each to contact electrically with one of a series of metal conducting-rings R, carried by the same shaft 0 which supports the distributer D, there being as manyof these key-levers K as there are key-levers on the type-writer which is to be manipulated.

R R, &c., are conducting-rings, which surround the shaft 0 of the distributer and are located adjacent to each other in the path of the free ends of the conducting key-levers K,

said rings being insulatedfrom each other,

Serial No. 394,258. (No model.)

as shown in Fig. 2. Each of these rings R is electrically connected to one of the distribufer-contacts p p, which are insulated from each other, the connecting-wires to being attached to said rings at different radial points corresponding with the radial location of the contact-plates p of the distributor.

On the under side of the lovers K is located an eccentric-shaft E journaled in the side of the frame F and provided with a switch-handle S, this eccentric-shaftbeing adapted to assume different positions, as shown at A and B, Fig. Land to either place the conductingrollers b in contact with the conducting-rings R, as shown at station B, or permit them to assume the position shown at station A,vas desired. 1

Each of the key-levers K is provided with a retractile spring .9, and is also connected by an independent conductor 10 to a corresponding magnet M, all of said magnets being,

connected electrically through the battery B to earth at E, as clearly shown in Fig. 2.

Each magnet M is provided with a bell: crank armature-lever a, which is connected by a link '21 to the free end of one of the typewriter levers K, said type-writer levers being provided with the usual link connections 25 and type-levers 'l, adapted to make the impressions upon the paper carried by the platen-roller P, as is well understood by those skilled in the art.

Any of the Well-known forms of type-writers now in general use in the market maybe utilized-in connection with my invention and the connection between the armature-levers a and the type-writer keys may be made in any preferred manner, my invention being directed, broadly, to the combination of a telegraph-circuit connecting two or more typewriters of well-known form so that they may be operated at will between two distant stations.

The distributers D are to be operated and controlled by any of the well-known methods of attaining synchronism between two constantly-revolving distributors. I have shown in Fig. 2 a pinion G, through which power may be applied to the shaft 0 in order to cause the distributer to rotate. Nor do I limit myself to a rotary distributer, as it is obvious that any form of distributor which will convey the current simultaneously to the different magnets in sequence both at the trans. mitter and receiver may be utilized and still fall within the scope of my invention.

I will now describe the operation of my improved apparatus, reference being had particularly to Fig. 1 of the drawings, wherein the switch 8 at the transmitting-station A is shown in the lowermost position, while at station B it is in its uppermost position,holding all of the key-levers K and their rollers b in contact with the conducting-disks R. The distributers having been adjusted to synchronism by any of the well-known methods and the type-writers having been supplied with paper preparatory to transmitting the message, the operator at the transmitting-station manipulates the key-levers K in the desired sequence, and as these levers are successively held down the current is transmitted through corresponding successive magnets M, conductors w, key-levers K, rollers b, conducting-rings R, and the corresponding segmentsp of the distributer,brush 0, line L, the duplicate segments 19, rings R, and keylevers K, magnets M, battery B at the receiving-station to earth, thereby causing the magnets M at both stations to be simultaneously actuated, their corresponding type-writer levers K making the necessary impressions upon the paper carried by the platen-roller P. When the carriages of the type-writers have reached their limit, each operator will restore them to the starting-point and advance the paper one line by hand in the usual manner; or, if desired, automatic mechanism such as is well knowntin the art of type-writing machines may be utilized for performing these functions.

If it is desired to utilize more than two typewriters, it will be understood that additional distributers with corresponding parts, key-levers K, and magnets H may he looped directly in the line, so that the current from the batteries B will pass directly through all of the distributors running in synchronism and through the corresponding magnets.

\Vhen it is desired to transmit from station A 'to station B, the operators, at those stations will simply reverse the positions of the switches S and proceed as before.

I do not limit myself to the use of the individual sets of key-levers K for controlling the operation of the magnets M, as it is obvious that the key levers K of the type writers themselves might be connected directly to the distributers, if desired; but I prefer to use the extra set of key-levers K, in order to adapt the apparatus to the application of ordinary type-writers with as little change as possible.

Having thus described my invention, what I claim, and desire to secure by Letters Patentof the United States, is
